I am running ArcMap 10.6. I am looking to find data on terrain heights for the continental US based on a lat/long. Is there a service for this anywhere under ArcGis or perhaps an online service? I am working with airline data and am drawing fishnets/tessellations of tracks based on AGL values. MK

I generated a tessellation with counts over the cont US for thousands of lat/long points. After joining data and setting quantity ranges for a heat map there is a lot of empty space. Drawing of the tessellation is also quite slow. Is there a way to mask out the empty polygons (0 value) and only display those with meaning? I imagine this would speed up the drawing as well.

I don't have the pro version. But I do have the spatial analysis add on. But I need more basic help on this one. I created a tessellation over the whole country (USA). It is very slow. I used a simple join from tessellation to the longitude field to test out and I can see highlighted hexagrams if I also apply a "Select by Attribute" on the Join shape file. But this is not what I am interested in. Is there any website/video that can help get me understand steps to get a point count heat map? Also I have tried PointDensity and Aggregation and these dont seem to take the tessellation as an input field. Also PointDensity has very odd distributions such as -1,307,732.125 -- -1,162,428.556... I know at least the coord projections are the same.

I have started using ArcMap 10.6 and need to create a heat map of point counts over the country. I am able to draw the fishnet over a smaller test area. What tool do I need to use to fill in the fishnet squares with graduated colors of point counts? I have tried numerous examples from google but they have not worked. My data set consists of only Lat/Long pairs in a file. I have converted these to shape files. I attached a small screen cap of what I am trying.
